Xiaomi Mijia Temperature and Humidity

Modern wearables are no longer just an accessory for measuring time, becoming full-fledged tools for environmental monitoring. Xiaomi Mijia Temperature and Humidity Electronic Watch is a unique device that not only shows the exact time, but also monitors the temperature and humidity in real time. To activate all the functions of this gadget, the user must perform the correct initial setup procedure through a smartphone.

The pairing process requires care, as Xiaomi’s ecosystem has its own characteristics of working with communication protocols. Incorrect sequences of actions can lead to the clock not being synchronized or showing incorrect data. In this guide, we will discuss in detail each step of the connection installation, from preparing software to fine-tuning notifications.

It is important to understand that the stability of the device depends on the quality of the application used and the version of the operating system of your phone. Android 4.4 / iOS 9.0 or higher is required for the correct operation of the watch, as well as the Bluetooth 4.0 module included. Ignoring system requirements often makes it impossible to find the device in the list of available for connection.

Preparation for the first start of the device

Before you try to connect the watch to your phone, you need to make sure it's fully operational. The device comes with a minimum battery charge, so the first step is to install the batteries or charge the built-in battery, depending on the specific model modification. If the device uses batteries, make sure that the protective film is removed and the contact is installed correctly.

The next critical step is to install the necessary software on your smartphone. Xiaomi’s smart home ecosystem is based on the Mi Home app, which acts as the central hub for managing all devices, and can be downloaded from official Google Play stores or the App Store.

Once the application is installed, you need to register for Mi Account or log in to an existing one. Without an account, synchronization of temperature and humidity data, as well as reading history, will not be available, and at this stage, it is recommended to check for updates for the application itself, as older versions may not support new communication protocols.

⚠️ Note: Before setting up, be sure to turn on geolocation (GPS) In the Android operating system, search for Bluetooth Low Energy devices (BLE) Unable to access location without active permission.

Installation and configuration of the Mi Home application

The functionality of the watch is only revealed when working in conjunction with the mobile application. After launching the Mi Home, the system will ask you to choose a region. This is one of the most important points, since the server on which your data will be stored and the list of available devices depends on the selected country. For most users, the best choice is the region of Russia or China if the device is intended for the domestic market of China.

The application interface may seem overloaded, but to connect the watch, we only need the home page and the device add menu. + In the upper right corner of the screen, the system will suggest scanning. QR-It's better to go manually, or wait for the app to find the gadget in range.

The process of pairing a watch with a smartphone

Direct connection is via Bluetooth Low Energy protocol, which ensures the energy efficiency of the device. Bring the watch close to the phone, at a distance of no more than 10-15 centimeters. On the smartphone screen in the Mi Home application, a pop-up should appear with a suggestion to add a new device.

If you don't detect automatically, go to manual add mode. In the device directory, find the "Wearables" or "Clocks" category. Select your model from the list. The app will start searching for the signal. At which point the confirmation code or pairing request may appear on the watch screen.

The dial is not just a picture, but an information bar. In the Mi Home app, go to the settings of the connected device and select the "Digs" or "Watches section Here you can choose both the temperature and the new model from the same. There is also a setup of units: degrees Celsius (°C) or Fahrenheit (°F). Some models allow you to adjust the refresh rate of the data on the screen. If you want to save battery power, set the refresh interval less often. If you want to monitor in real time, select the minimum interval. Remember that the frequent on the screen and the operation of the sensors consume energy. Also in this section you can adjust the brightness of the backlight and the time at which the screen will go out.

The most common problem is that the clock stops syncing or the temperature data is not updated, often due to loss of Bluetooth connection, check whether the Bluetooth on the phone is disabled and whether the device is within range. Another common problem is that sensors are not reading correctly. If the watch is showing temperatures that are significantly different from room temperature, make sure that they are not near heat sources (battery, computer, direct sunlight). 15-20 If the device is stuck and does not respond to pressing, perform a forced reset. This usually requires pressing the control button on the 10-15 You can, in extreme cases, completely reset to factory settings through the app menu by selecting "Delete device" and "Reset settings: 1. Open Mi Home. 2. Click on the device icon. 3. Select three points in the corner (Settings). 4. Scroll down to "Delete the device". 5. Confirm the action. If none of the above helps, maybe the problem lies in the hardware or firmware version. Check for firmware updates in the device settings in the application. The manufacturer regularly releases patches that correct the errors of the Bluetooth module. Why does the watch discharge quickly? Fast discharge can be caused by high screen brightness, frequent updates of weather data or active use of the phone search. Try to reduce the brightness and increase the synchronization interval. Also try not to keep the watch at extremely low temperatures. Can you wash the Mijia watch under water? Most models of the Mijia Temper and Humity are designed to protect them from water, but we do not use it with the sensors from the water? The language of the watch interface usually depends on the language of the smartphone system or the region selected in the Mi Home app. There is often no separate language setting inside the watch. Try changing the language of the phone system to English or Russian and reconnect the device.
